Founded in 1992 as the American Society of Interventional and Therapeutic Neuroradiology (ASITN), the Society of NeuroInterventional Surgery (SNIS) is a scientific and educational association with over 600 members worldwide. The SNIS is dedicated to advancing the specialty of neurointerventional surgery in order to provide the highest quality of patient care to the public. SNIS draws its membership from three areas - interventional neuroradiology, endovascular neurosurgery and interventional neurology. It's the bringing together of these three subspecialties under one umbrella that gives SNIS its diversity and strength.
